So I began to look at other instances in which the nervous system is being stimulated on a daily basis and discovered that sports science has a lot to teach us about this. Whether you are practicing yoga, meditation, using brainwave entrainment, or working out, it’s all pushing the nervous system. One of the things that sports science teaches us is that the nervous system waxes and wanes like a sine wave in its capacity to recover from, and grow from, the stimulation we give it every day. Static levels of stimulation, where you’re getting the same smack every day, day in and day out, do not allow for the fact that there are times when the nervous system is at its peak to handle the stimulation, and there are other times when the nervous system is in its trough, or valley period, when it is harder for it to recover from stimulation.
The Transparent Corp forum – This forum is an invaluable resource for any brainwave entrainment user or enthusiast. Most of the feedback is obviously focused on the Transparent Corp software, but with over 20,000+ posts now you can find answers to the whole array of brainwave entrainment questions on there. (UPDATE: Sadly, the Transparent Corp forum has now been taken offline)
Stress: In one randomized controlled trial with 108 participants, a single session of alpha and delta stimulation resulted in significantly less anxiety in surgical patients. Another session of theta stimulation resulted in improvement in certain measures of stress. Stimulation with certain frequencies of alpha and beta were reported to provide the most significant benefit for those who are stressed.
Clinical testing of Brain Sync programs resulted in a record-breaking 87% success rate. They are offered to patients at America's most prestigious hospitals such as Sloan Kettering and Dana Farber Institutes. EEG studies conducted at Harvard Body Mind Medical School, and UCLA concluded that Kelly Howell's Brain Wave Audio Technology® prompts brain activity into extraordinary body-mind states. Vist our Research Findings page for a full list of articles from the Harvard Medical School, the U.S. National Institutes of Health and Psychology Today that concur: the benefits of guided meditation, binaural beats, brainwave entrainment and positive subliminal messaging are real and profound. To learn more see this article about brainwaves in Scientific American.
The eyes of the participants were closed and the VFP goggles illuminated in alternative manner; first the right eye, then the left. The rate at which the photic stimulation was conducted ranged between 0.5 Hz and 50 Hz. Of the 50 patients with migraines, 49 considered their headache as having been “helped” by the stimulation and 36 noted that their headache had completely “stopped” from the VFP goggles.
Biofeedback enhancement: In 1981, researcher Arturo Manns discovered that 15 minutes of stimulation with isochronic tones enhanced biofeedback protocols for bruxism (grinding of teeth). They did this by increasing muscle relaxation superior than standalone biofeedback. Brainwave entrainment is different from biofeedback in that it does not allow the person to consciously control their brainwave state.
Hi Amandeep. I am so sorry to hear you are having these troubles. I am not familiar with Marisa Peers materials, so I cannot comment on this, but I can tell you we have never had an experience like this reported from using the audios we offer on this site. I would cease any and all hypnosis or brainwave entrainment audios, and contact your doctor. The issues you are mentioning sound like they could be a physical issue that may be related to more than the audios you’ve listened to.
Applying brainwave entrainment in the alpha range may result in benefits similarly found with Zen or Transcendental Meditation. These benefits extend throughout the body and include improved breathing patterns, higher physical energy levels, an improved outlook, increased sports performance, improved relationships, and increased workplace satisfaction and performance … just to name a few.
Mood: While brainwave entrainment may not be a great option for depression, particularly in the slower frequency ranges, beta entrainment may improve certain measures of mood. Additionally it is important to consider the fact that many people experience detrimental changes in mood as a result of heightened stress and anxiety. Since brainwave entrainment has been shown to improve stress and relaxation, overstressed individuals may experience a simultaneous mood improvement.
Another general benefit of using brainwave entrainment in general is that it increases and promotes whole-brain functioning, meaning that the two hemispheres of the brain grow more connections and exchange information more easily. This can help more starkly rational people become more intuitive, and more airy-fairy people become more focused and logical.
Isochronic tones work by influencing your brainwave activity and they can’t directly affect the body. That said, the brain does control the body, so sensations and feelings can sometimes be felt in the body after stimulating your brainwave activity. Some people who are new listeners of this type of audio can sometimes feel tingling sensations in their body. Not everyone feels this and these sensations usually stop once you get more used to using the audios. Isochronic tones are considered as a safe technology. However, sometimes they can leave you feeling temporarily fatigued, especially if you listen to them for an extended period (hours) when you first start using them. If you felt fatigued, I would recommend using them for a much shorter period while you are getting used to them and ensure you are well-hydrated.
So my question is: Why? When I read it, I had a bit of a fear of brain aneurysms. Therefore, 1. could someone contact me to tell me why use of your product shouldn’t continue past 2 hours? [I probably won’t heed the reason unless it’s a life or death warning: I love this product that much!] 2. Please feel free to post my letter in your testimonials, if you ever decide to post such customer comments.
I tried other companies the last few years or so….among the likes that mainly used binaural audio and the deepest I was really ever to achieve was alpha state….maybe theta once or twice over the last few years. It takes incredible dedication and practice to achieve the deep, renewing states of meditation that are most sought after…..I listened to the theta meditation mp3 last night and within what seemed like a few minutes my mind was flooded with imagery…memories long gone…my body was sleeping, heavy as lead, but my mind was crystal clear, aware of my surroundings. I could barely even open my eyes!
So using the example track above, the right ear is sent a 20Hz beat, compared to a 10Hz beat in the left ear. As the right ear receives the higher frequency of beat, this works to increase the speed of the ‘left' brain hemisphere, which can be helpful for people with conditions like ADD, who are often found to have an abundance of slow wave activity in the left brain.
Generally speaking, the brain will usually entrain to the strongest stimulus which would be isochronic tones over binaural beats. So when you see people add binaural beats at a different frequency to the isochronic tones, that would not produce additional brainwave entrainment at another frequency. If they are both at the same frequency I haven’t seen any research to indicate whether that would be beneficial or not, but my belief is that it would weaken the potential for entrainment. When you look at the waveform of an isochronic tone there is a distinct empty space between each beat, making it very pronounced and effective. When you add binaural beats at the same frequency it looks like this: http://www.mindamend.com/wp-content/uploads/2017/11/isochronic-tones-binaural-beats-combined-waveform.jpg. The depth of the waveform is now half as deep and less effective. This is before the binaural beats are formed inside your head, where the waveform is hard to determine and measure. From listening to that type of combination the beats sound much less pronounced, which has to make them much less effective in terms of a brainwave entrainment stimulus, compared to isochronic tones on their own.
One can also learn to control and slow down their brain waves through various neurofeedback technologies such as electroencephalograph (EEG), galvanic skin response (GSR), and heart, pulse and breath rate monitors. These devices measure stress and relaxation parameters and then "play" back the signals to the user so they can use the signals as a beacon to guide and "steer" themselves into a relaxed state. This takes some time, work and discipline but is much quicker than learning meditation.
Altered states of consciousness: In as early as 1987 it was discovered that photic stimulation at specific frequencies produced an altered state of consciousness. An extremely small study with just 4 individuals involved photic stimulation at 6 Hz, 10 Hz, and 18 Hz. The results were reported to have altered their conscious awareness. This really isn’t that surprising to anyone that’s used brainwave entrainment therapy.
The objectives and inclusion criteria of the review were clear. Relevant sources were searched for studies, although the restriction to published studies in English meant that the review was prone to publication and language biases. The authors did not state whether steps were taken to minimise the risk of bias and error in the processes of study selection and data extraction (for example, by having more than one reviewer independently make decisions). The authors mentioned which studies were blinded, but it did not appear that study validity was systematically assessed, which made it difficult to judge the reliability of the review findings. The decision to combine studies by narrative synthesis appeared appropriate given the strong clinical heterogeneity between the studies, but the authors failed to quantify the size or statistical significance of the findings reported. The evidence presented appeared to justify the authors’ conclusions that further research was justified, but in view of the dearth of good-quality evidence and problems with methodology and reporting in the review, the conclusions regarding efficacy did not appear reliable.
